Objective For certain condylar fractures, extracorporealization of the condylar segment may be performed via extra-oral vertical ramus osteotomy (EVRO) to facilitate reduction and fixation. This approach can similarly be used for condyle-sparing resection of osteochondromas of the condyle. Due to controversy regarding long-term health of the condyle after extracorporealization, we investigated the viability of this technique through a retrospective analysis of outcomes. Methods Twenty-six patients were treated using EVRO with extracorporealization of the condyle for both condylar fractures (18 patients) and osteochondroma (8 patients). Of the 18 trauma patients, 4 were excluded due to limited follow-up. Clinical outcomes were measured, including occlusion, maximum interincisal opening (MIO), facial asymmetry, incidence of infection, and temporomandibular joint (TMJ) pain. Radiographic signs of condylar resorption were investigated, quantified, and categorized using panoramic imaging. Results Average follow-up was 15.9 months. Average maximum interincisal opening was 36.8 mm. Four patients demonstrated mild resorption and one patient demonstrated moderate resorption. Two cases of malocclusion were attributed to failed repairs of other concurrent facial fractures. Three patients reported TMJ pain. Conclusions Extracorporealization of the condylar segment with EVRO to facilitate open treatment of condylar fractures is a viable treatment option when more conventional approaches prove unsuccessful.
